Well, it's war.
Last week the street fight between the education reform crowd in Nashville and the Metro Nashville Public Schools bureaucracy went nuclear, when Schools Director Jesse Register announced that, to wit:
a) He had hired an attorney to look into the legitimacy of charter schools.
b) His attorney had found grounds that charter schools in Tennessee are unconstitutional.
It was the culmination of months and even years of gradually increased hostilities, in which finally one side just couldn't wait to rip the other side a new one.
The timing was awful. Days earlier, state test results had shown glowing results for Nashville charters. Then the schools director announced probable cause for their annihilation.
